Removed: No Longer Available
Chest Trapper was removed from the game files, and is no longer obtainable.
Chest Trapper was a unique monster that was never implemented in game, although its assets existed in the game files. Its appearance resembled basic storage chests and came in two varieties, Royal Chest and Medieval Chest.
These were not capturable. The game assets for this monster were removed during update Glad Giraffe's overhaul of unique monsters.
